Abstract: Implementations described and claimed herein provide systems and methods for evaporative cooling control. In one implementation, a humidity setpoint is received for a designated space, and at least one atmospheric condition of ambient air is received. The at least one atmospheric condition is measured using one or more ambient air sensors. A performance prediction of an evaporative cooler is generated by calculating a set of one or more predicted psychrometric properties of supply air leaving the evaporative cooler based on the at least one atmospheric condition. The humidity setpoint is compared to the set of one or more predicted psychrometric properties of the performance prediction in a setpoint comparison. A flow of fluid is controlled over evaporative media using one or more pumps of the evaporative cooler. The flow of the fluid is controlled based on the setpoint comparison such that the humidity setpoint is prevented from being exceeded.

Generating millimeter-wave oscillations may involve providing a semiconductor device comprising at least two terminals and a polar heterojunction formed from two semiconductor materials. A voltage bias may be applied to at least two terminals of the device in which the voltage enhances a two-dimensional electron gas (2DEG) layer at the polar heterojunction and produces a sharply-peaked but spatially-localized electric field within the 2DEG with a large longitudinal component, wherein the longitudinal component of the electric field serves as a nucleation site for a plurality of propagating dipole domains observable as a plurality of self-sustaining millimeter-wave oscillations.

The base can be disposed substantially between the emitter and collector. The base can comprise a plurality of alternating type-I and type-II layers arranged to form a short period super lattice. The type-I layers can have a band-gap that is narrower than the band-gap of the type-II layers. At least one of the type-I layers and the type-II layers can consist essentially of a quaternary material.

Abstract: An InGaAs/InAlAs-based avalanche photodetector provides high gain and high bandwidth over a range of operating biases. A graded transition region alleviates the barrier to electron transport from the absorption region to the multiplication region when an operating bias is applied. The graded transition region is a graded bandgap material with a relatively wide bandwidth in the region closer to the multiplication region and a relatively narrow bandgap in the region closer to the absorption region. In another embodiment, a p-type dopant profile is introduced within the absorption layer to produce an electrostatic field which accelerates electrons towards the multiplication region. In another embodiment, a bi-level multiplication region with a wide bandgap ternary layer and a narrower bandgap quarternary layer is provided at an increased thickness to improve gain per unit length.

Abstract: The present invention is directed toward an edge detecting photodiode that includes a waveguide comprising a p-doped InP cladding layer, an n-doped InP cladding layer, a p-side waveguide layer, an n-side waveguide layer, and an InGaAs absorption layer therebetween, in which the absorption layer is doped to have an absorption region and a depletion region that, when under bias, will overlap by an amount sufficient to substantially balance the transit time of positive and negative charged carriers across the waveguide. The photodiode is preferably formed on an InP substrate. The photodiode preferably has a planar polymer layer in contact with the InP substrate. The polymer layer also preferably has a ridge formed therein for the photodiode waveguide. The polymer layer may have a coplanar transmission line deposited thereon, and a pair of metal-insulator-metal (“MIM”) capacitors may be incorporated into the coplanar transmission line.
